Application filed August 17, 1910. Serial No. 577,659.

To all whom it may concern:

Be it known. that l, Ennn G. Wmnons, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useiul Improvements in Valves, of which the following is a description, referencebeing had to the accompanying drawings, forming part of this specification.

My "ivention relates more particularly to valves for controlling and regulating" the relative supplies of hot and cold water, and is illustrated in the accompanying drawing as embodied in a shower-valve, or valve adapted to form part of a showcr-beth fixture.

It has for its object the provision of a simple and eilicientvalve of this character in which the supplies of hot and cold water may be regulated and controlled as desired.

In the accompanying drawings,- Figure 1 r is a middle vertical section of the valve in the plane of the pipe connections for the hot and cold water supply pipes; Fig. 2 a corresponding view at right angles to the view in Fig. 1; Fig. 3 a horizontal section on the line 3-3 of Figs. 1 and 2; and Fig. 4: a

horizontal section on the line d-4t of the same views.

The same letters of reference are used to indicate corresponding parts in the several views.

The main casing of the valve comprises at hollow body portion or shell A provided upon its opposite sides with the pipe connections B and C for the hot and cold water supply pipes, respectively, and midway between them, at one side, with a connection B for the delivery pipe which leads upward to the shower-head, and at its opposite side with econnection C for the flexible hose connected with the usual shampoo-head. In use the valve casing will be secured in the position shownin Figs. 3 and 4, with the connection B projecting upward and the axis of thevalve chamber and valve lying horizontal, and in describing the details of construction shown in Figs. 1 and 2 the terms upper and lower and similar ones will be'used with reference to the relative positions of the parts in. those figures.

The pipe-connections 'B and C communicate by tubular passages l) E formed within the shell A of the casing, and by ports F and G, Fig. l, with a central cylindrical velvechamber H, whose lower end, at the bottom the operating handle N by which it may be turned. The sleeve ,or nut L is'provided:

upon its opposite sides with projecting lugs or Wings O@ which fit in vertical grooves or guideways P formed for them upon the. inner surface or the cylindrical upper end of a, cage Q which is externally threaded and screwed into the internally threaded upper end of the main casing A, and which projects downward into the latter and provided at its lower end with an inturned annular flange or ring which seats against the upper .cnd of the cylindrical wall of the valve chamber H, a leather or other suitable peel:- ing ring It being interposed between the two toforn'i a tight joint, and to also form a valve seat for the valve J, which seats against the under side of the ring It as shown. The lowerportion of the cage Q}, within the casing A, is provided with ports S which atlord free communication between the interior of the cage and the chamber within the casing A. Surrounding the externally threaded upper-portion of the'cage Q, and clamped. betwe'en the cylindrical upper end. of e body portion A of the main casing and a superimposed cap portion A which is screwed upon the upper end of the externally threaded pox tion oi the cage Q, is an indicator plate or tlisk U, shown in plan view. in Fig. 3, provided with suitable words or signs to indicate the various positions ofthe valve,

and with which coilpcrates a pointer V upon the hollow hub VI of the operating handle N, Fig. 1, said hub fitting and turning upon the reduced upper (lid of the cap piece A. of the casing, and being provided in its upper portion with a polygonal opening to fitnpon the correspondingly shnped upper end of the spindle iii. A screw K serves to secure the handle to the spindle. The spindle M is pro vided with an annular collar or shoulder Y which. bears againstthe under side of the upper end of the cap piece-A of the casing,

and the latter contains a'stuiiing box Y surrounding the spindle M to prevent. leakage.

As will be understood from the foregoing, the valve J carried by the stem K de pending from the internally threaded sleeve or nut L may be lowered from its seat R,

. andiraised-thereto, by turning the ope-rat ing handle ll,'-and 't he valve be thereby 1; opened and closed. When the valve is in its F, whilethe cold water inlet port G is left wide open. The cold Water supply is there: fore normally admitted to the interionof the valve. chamber ll, beneath the valve J, but cannot escwe from the upper end of the chamber so ong as the valve remains seated. The chlimber is provided in its opposite walls with two longitudinal recesses or bypasses 11, Figs. 2 and at, which extend fromthe horizontal plane or" the cold water inlet when the valve J is unseated. these by-passes permit the cold water supply to escape past the valve, through the valve seat at, the u per end of the chamber, to the interior of t 1e casin A. whence it oasses throu h the deliv n i l g ery-pipe connection B to the shower-head. A depression of the valve 3 merely sufiicient to unseat it, as ellected, for instance, by a quarter turn of the operating handle N, will ply only to the fixture, while further depression of the valve, ellected by a half-turn of the operating handle, will serve to partially close the cold water inlet port G and partially open the hot Water inlet port F, and

thereby admit both h and cold water to the interior of the casing A, and thus cause a supply of mingled hot and cold, or warm,

25 port G to the upper end 01' the chamber, and

35- therefore serve to admit the cold Water supwater to be supplied to the showenhead. A

further and complete depression oithe valve J, as by a three-quarter turn of the handle N, will serve toentirel y close the cold Water inlet port G and fully open the hot water inlet F, to admit hot water only.

These several positions of the operating handle are readily determined by means of the pointer V carried by it and coiipcrating with the indicator plate U. The latter is made adjustable around the valve casing, so

5 that its several indications may be brought to proper-position, in assembling the valve, to coii perate with the pointer V. Thus, the word Oil. on said plate, indicating that the valve is closed, must underlie the pointer V when the valveds in fact closed; In assembling the parts of the valve structure, therefore, the indicator plate U is left loose, between the upper end of the body portion of the casing A and the lower end of" the can piece it, until the proper position tor it is determined by turning the handle and pointer until the valve is tightly closed, whereupon the plate is adjusted to proper position and then firmly clamped therein by tightening the cap-piece A upon it.-
